Follow up: With start-foreground I'm able to see that skipACL=yes was effective (full output in the end of the email):
2016-07-21 20:36:19,433 [myid:] - INFO [main:PrepRequestProcessor@87] - zookeeper.skipACL=="yes", ACL checks will be skipped What is the problem with the other config values? I'm trying to boost performance by disabling the persistency of zookeeper. I'm only interested in using zookeeper in memory database (no need for data persistency after reboot). Any advice on how to achieve this?
